The heated debate that resulted was settled by the
Bundestag (Germany's parliament) only on 20 June 1991. By a vote of 338–320,
[6] the Bundestag voted to move the seat of government to Berlin. The vote broke largely along regional lines, with legislators from the south and west favouring Bonn and legislators from the north and east voting for Berlin.
[7][8] It also broke along generational lines as well; older legislators with memories of Berlin's past glory favoured Berlin, while younger legislators favoured Bonn. Ultimately, the votes of the
eastern German legislators tipped the balance in favour of Berlin.
